yes yes YES!!!!!!! IHAVE FOUND THE SOLUTION!!!!
ps: if it was on a diff post don't tell me! let me enjoy my glory

easy to get python, uknmp, kagu to install in a breeze
1st-do what the uy above said and clear ur device of all the repo ALL OFF Them!

2nd- create a new repo in the app manager
-name it whateva u want
-type this url http://stage.maemo.org/extras
-here's the catch that made it impossible for apps to install, make sure th distribution box is EMPTY that's what made the app manager crash!
-components: free non-free
- that's it!

3rd- i recomend you install python runtime first as in case it fails again you allready will have what you need!

4th- Download and install all u want, it all works for me !!

i spend the last 3 hours experimenting untill it finally worked! i am going to make a thread of this announcement so all the new users have some guidance
